CVSps is a program for generating 'patch set' information from a CVS repository. A patch set in this case is defined as a set of changes made to a collection of files, all committed at the same time (using a single 'cvs commit' command). This information is valuable for seeing the big picture of the evolution of a CVS project. While CVS tracks revision information, it is often difficult to see what changes were committed 'atomically' to the repository.
